Buckwheat is made from the fruits of the herbaceous plant buckwheat (Fagopyrum), which grows everywhere, except in the far North, blooming with yellow fragrant flowers.

Buckwheat (or buckwheat, as it is usually called) is of several types-the kernel-buckwheat seeds without a fruit shell, steamed or not steamed; seeds - buckwheat kernels of coarse grinding, flakes-flattened kernels.

Buckwheat flour, which is gluten-free, is produced by grinding all the same kernels.
